Description

Technical Field

[0001] The present invention relates to a system, comprising a hollow profile, wherein the hollow profile has a fixed wall and at least one inner wall, and a hinge component of a hinge hinge, wherein the hinge component is fixed to the fixed wall, wherein the hinge component comprises a mounting component and an adjustment component, wherein the mounting component can be fixedly mounted on the hollow profile and has a plurality of positioning protrusions, wherein at least one of the positioning protrusions is configured as an expansion anchor bolt, and the adjustment component can be moved along a moving direction relative to the mounting component and can be fixed at a desired moving position. Background Art

[0002] Such a system is known from EP 2 504 511 B1.

[0003] In such a system, the mounting member comprises at least one positioning projection for engaging at least almost without play in holes in the fixing wall and the inner wall, and at least one second positioning projection for engaging at least almost without play in the hole in the fixing wall alone.

[0004] Although it has been shown that with this system it is possible to transmit high holding forces from the hinge part into the hollow profile, in particular when the locking projection is designed as an expansion anchor, i.e. measures are provided by which the outer diameter of the locking projection can be enlarged at least over a portion of its length in order to be able to bear against the outer circumference against the fastening wall and the edge of the hole in the inner wall, it has also been shown that, simply by mounting the mounting part on the hollow profile, undesirable permanent deformations can occur in the region of the fastening wall. Summary of the invention

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a system which is improved in this respect.

[0006] This object is achieved by the system defined in claim 1. The invention also relates to a hinge component of such a system and to a hinge having such a hinge component.

[0007] In the system according to the invention, the positioning projection is adapted to the hollow profile such that the positioning projection engages only in a hole provided in the fixing wall.

[0008] Surprisingly, it has been found that it is usually sufficient for the locking projections to simply engage in the fixing wall in order to be able to transmit the required amount of force between the leaf and the frame. This is particularly true if the locking projections are all designed as expansion anchors, so that their outer circumference rests on the edge of the hole in the fixing wall after the mounting part has been installed. Since, contrary to the teaching of EP 2504 511 B1, no locking projections interact with the inner wall of the hollow profile, permanent deformation of the fixing wall caused solely by fixing forces is reliably avoided.

[0009] If, as is often the case, the hollow profile is a plastic profile whose inner wall is metal-reinforced, it is also advantageous in the system according to the invention that the holes for the positioning projections only have to be produced in the fixing wall made of plastic and no longer need to be produced in the inner wall, which may be metal-reinforced. Thus, in the system according to the invention, the workload is reduced on the one hand. On the other hand, the undesired generation of metal chips during the assembly process is avoided.

[0010] In order to make optimal use of the forces transmitted from the leaf into the frame according to the system of the invention, it is advantageous if all locking projections are designed as expansion anchors.

[0011] Preferred embodiments of the positioning projections include expansion pins or expansion screws. The use of expansion screws has the advantage that the expansion effect can be eliminated again by unscrewing the expansion screw, so that the mounting component can be removed from the hollow profile again after the installation is completed. When using expansion pins, the installation component can usually be installed faster, because, for example, the expansion pin only needs to be hit once with a hammer to be driven into the expansion anchor, thereby achieving the positioning function.

[0012] In a particularly preferred embodiment of the system according to the invention, the positioning projection is arranged on the mounting component in such a way that the positioning projection passes through the adjustment component in one or more linear guides extending in the displacement direction. The positioning projection then serves both during adjustment and in the desired adjustment position to guide the adjustment component, whereby further measures for guiding the guide component can be omitted.

[0013] In order to improve the guiding effect and thus the adjustability of the adjusting element, it is advantageous if at least two locking projections are part of a guide element which passes through a linear guide of the adjusting element.

[0014] The guide element is preferably configured in a groove-like manner, has longitudinal walls that are opposite to each other, and is configured such that its open side is arranged toward the fixed wall.

[0015] If the wall section extending obliquely, curved or transversely to the longitudinal wall (which can be part of the positioning projection) is designed to be slotted so that the expansion of the positioning projection also leads to an increase in the distance between the two longitudinal walls of the guide element at least in a partial area, it can be achieved that the adjustment part passes through the linear guide without play at least in a partial area. This further increases the adjustment accuracy that can be achieved in the system according to the invention.

[0016] Independent of whether the positioning projections are part of the guide element (the positioning projections pass through the linear guide mechanism of the adjusting component), in order to improve the adjustment accuracy that can be achieved using the system according to the invention, it is preferred that the positioning projections are constructed so that they can be expanded at least in a direction inclined or perpendicular to the movement direction, in the area where the positioning projections pass through the adjusting component in the linear guide mechanism.

[0017] The invention also relates to a hinge part of the above-mentioned system and a hinge part equipped with such a hinge hinge. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1The illustrated embodiment of the system 100 according to the invention comprises a hinge part 1 having an adjustment part 2, on which a hinge part 3 is formed, which includes a receptacle 4 for an adjustment bushing of a hinge pin, which is not shown in the figure but is known per se. In the adjustment part 2, two linear guides 5 are provided, which extend parallel to each other and perpendicular to the longitudinal axis of the receptacle 4, in the form of slotted through holes 6. A transmission element 7 is provided in the middle between the slotted through holes 6. The transmission element 7 is designed in the form of a pin and is located in a bore 8 of the adjustment part 2. The transmission element 7 has a threaded hole 9 extending transversely to its longitudinal extension, in which an adjustment spindle 10 adapted to the threaded hole 9 engages.

[0027] The adjusting spindle 10 is supported in a mounting part 11 of the joint part 1 so as to be rotatable about its longitudinal axis and fixed in the direction of its longitudinal axis, so that its longitudinal axis is oriented parallel to the longitudinal extension of the linear guide 5. For this purpose, the adjusting spindle 10 is arranged in a spindle receptacle 12 and has a cylindrical spindle head 13, which is supported in the longitudinal direction of the spindle on mutually opposite supporting surfaces 14, 15 of the spindle receptacle 12.

[0028] The mounting part 11 also includes guide elements 16 which pass through the through hole 6 over a portion of the length of the linear guide 5. As a result, the assembly comprising the adjustment part 2 and the hinge part 3 can be moved in a movement direction V which extends parallel to the longitudinal extension of the linear guide 5.

[0029] The guide elements 16 are designed in a channel-like manner, so that in the installed state their open sides each face toward a fastening wall 17 of the hollow profile 18 .

[0030] The guide element 16 is formed on a rear side 19 of the mounting part 11 which faces the front side 20 of the adjusting part 2 and rests against the fastening wall 17 of the hollow profile 18 when mounted on the fastening wall 17 .

[0031] In addition, a positioning protrusion 21 is provided on the mounting part 11. A positioning protrusion 21 is formed on each longitudinal end of the guide element 16, so that the positioning protrusion 21 is a part of the guide element 16.

[0032] Each positioning projection 21 has a length L that is adapted to the hollow profile 18 so that the corresponding positioning projection 21 only passes through the fixing wall 17 in the hole 22 but does not pass through the inner wall 17 a of the hollow profile 18 .

[0033] The positioning projections 21 are tubular and have longitudinal slots 23, wherein two longitudinal slots 23 are arranged in each case so that they are penetrated by a plane E extending parallel to the longitudinal side 24 of the guide element 16. Thus, the outer circumference of the positioning projections 21 can be expanded over the length of the slots 23, for example by screwing an expansion screw 25 into the respective positioning projection 21. Thus, the positioning projections 21 have the properties of an expansion anchor.

[0034] At least the slot 23 penetrated by the plane E extends at least to a position close to the back side 19 of the mounting part 11. This results in the guide element 16 being stretched out at least in the region of the positioning projection 21 in a direction perpendicular to the plane E under the action of the expansion screw 25, so that the guide element 16 is pressed against the longitudinal side 26 of the through hole 6 with its longitudinal side 24 at least in a partial region. Therefore, screwing in the expansion screw 25 not only positions the mounting part 11 on the fixing wall 17 of the hollow profile 18, but also compensates for any gaps between the longitudinal side 24 of the mounting part 11 and the longitudinal side 26 of the through hole 6 and ensures a clearance-free fit of the hinge part 1 on the hollow profile 18. Due to this measure, the hinge part 1 and the system 100 containing this hinge part 1 are characterized by particularly precise and reproducible adjustability in the adjustment direction V.

[0035] In the embodiment of the hinge part according to the invention shown in the drawings, additional holes 27 are provided in the mounting part 11. The additional holes 27 penetrate one of the guide elements 16 in each case in a tubular projection 28 in the corresponding guide element 16. The projection 28 also has slots 23, which are penetrated by the plane E. This ensures that the longitudinal sides 26 of the guide element 16 can be expanded in the direction of the longitudinal side faces 24 even in the region of the projection 28, so that the longitudinal side faces 24 can be pressed against the longitudinal sides 26 of the through-hole 6 under the action of the expansion screw 25 even in the region of the projection 28. The additional holes provide the possibility of screwing additional fixing screws (not shown in the drawings) into the fixing wall 17 of the hollow profile 18 as required, if this is necessary in order to obtain the necessary holding force on the profile in individual cases.
